OBJECTIVE: To remind the concerned party of the importance of safe and rational use of drugs and the reevaluation of drugs after they have been put into market. METHODS: To analyze the occurring process and the treatment of six death/disability cases related to adverse drug reactions in Ningxia area as well as the problems existed in the management on safe drug use and the solutions. RESULTS & CONCLUSIONS: Management on safe drug use should be reinforced within the system of health and drug administration, and great importance should be attached to the reevaluation of drugs after they have been put into market to ensure safe and rational drug use.

OBJECTIVE: To investigate the protective immunity in mice immunized with rEg.EF-1 and its potential as vaccine candidate.METHODS: ICR mice were subcutaneously immunized with rEg.EF-1 for three times(with an interval of 2 weeks) and challenged with Eg 2 weeks after the completion the immunization,sacrificed at 20 weeks after infection with Eg.The rate of reduced hydatid cyst and the levels of IgE,IgG and IgG subclasses in sera were examined by enzyme linked immunosorbent assay,with adjuvant group as control.RESULTS: As compared with adjuvant group,the immunoprotection ability(rate of reduced hydatid cyst) in rEg.EF-1 group was 85.6%;The levels of IgG,IgG1 and IgG2a in mice immunized with rEg.EF-1 significantly increased(P0.05),and no significant difference was noted in IgG3 and IgE levels.CONCLUSIONS: The rEg.EF-1 antigen could induce certain immunoprotection,suggesting the potential of rEg.EF-1 as an vaccine candidate.

Thyroidectomy provides rapid solution of hyperthyroidism and the goal of perioperative management is to make patient as close as possible to euthyroidism clinically and biochemically before surgery.It is recommended to target at the thyroid hormone synthetic,secretory,and peripheral pathway with concurrent treatment to correct any latent decompensation of normal homeostatic mechanisms.

Aim To explore the antitumor active metabolites of marine-derived Streptomyces flavorectus Z4-007. Methods The separation procedure was guided by a flow cytometric bioassay using tsFT210 cells to examine cell cycle inhibitory activity, and various column chromatography using silica gel, Sephadex LH-20, and ODS were employed for the isolation and purification of bioactive compounds. Chemical structures were investigated by spectroscopic methods and biological activities were evaluated by flow cytometry using mouse cancer tsFT210 cells. Results Four bioactive compounds were isolated from the fermentation broth of Streptomyces flavorectus Z4-007, one of them had been identified as 1-(2,4-Dihydroxy-3,5-dimethyl-phenyl)-hexa- (E,E)-2,4-dien-1-one (1) and the other three compounds were considered to be peptide, Compound Ⅰ inhibited the cell-cycle of tsFT210 cells at the G_0/G_1 phase at higher concentrations, while at the lower concentrations compound Ⅰ inhibited the cell-cycle mainly at the G_2/M phase, accompanied with induction of apoptosis in the tsFT210 cells.Conclusion Compound Ⅰ was isolated from the metabolites of the genus Streptomyces for the first time and provided as a new cell-cycle inhibitor.

Objective To set a RFID(Radio Frequency Identification) system for Gold Immunochromatographic Assay by using RFID-reading module,RFID tags and the master-MCU.Methods Radio frequency technology is characterized by the automatic identification and large dada-storage capacity.Electronic tags were packed with Gold Immunochromatographic Assay(GICA) strips and such data were stored in electronic tags as strip information,the test results,the identity of the tested,the test date,etc.The information were transmitted to PC through the RS-232 serial port,thus realizing the rapid and accurate recording and management of data.Results The application of RFID guaranteed the proper use of Gold Immunochromatographic Assay strips and improved the efficiency of sample management and data storage.Conclusion The application of RFID to Gold Immunochromatographic Assay can be used in general investigation of epidemic situation,biomedical detection and other relevant fields.

Objective:To assess clinical value of grading scale for intracerebral hemorrhage(ICH).Methods:By using the grading scale for ICH suggested by Hemphill and colleagues, 205 patients with acute ICH presenting to our department during 2000～2001 were studied retrospectively.Results:Thirty-mortality of ICH patient increased steadily with ICH Score.Conclusion:The grading scale for ICH is a simple amd reliable method of ICH score,worthy of clinical application.

Objective:To Construct a prokaryotic expression vector of cystatin C(Cys C)to provide a basis of purify Cys C protein produced by the expression system.Methods:Total RNA was isolated from HL-60 cells,and human Cys C gene was amplified with RT-PCR.The cDNA fragment was cloned into pET32a(+)vector,which was confirmed with sequencing and electrophoresis.Results:The result of electrophoresis showed that Cys C had been cloned into pET32a(+)vector,and the result of.DNA sequence analysis also showed the cloned Cys C gene sequence was completely correspondent to GeneBank data.Conclusion:The prokaryotic expression vector of cystatin C(Cys C)was obtained,providing a basis of purification of Cys C protein produced by the expression system.

Objective To study the adhesion and proliferation of rabbit bone marrow mesenchymal stem cells(BMSCs) on the HA/TCP bone graft scaffold.Methods BMSCs were harvested from the iliac bone and obtained by using adhesive culture method.BMSCs were induced with osteogenic medium,at the 7th day,the cells were stained by the calcium cobalt method to show the activities of alkaline phosphatase(ALP).At the 10th day,the mineralized nodules of osteoblasts stained with chinalizarin.Otherwise BMSCs were induced with adipogenic medium,and at the 21st day the cells stained with oil red O.We cultured the BMSCs on the surface of a matrix scaffold with osteogenic medium.The morphologic characters were checked by light microscopy,fluorescence microscopy and scanning electronic microscopy,and the proliferation of BMSCs were assayed using the MTT test.Results At the 7th day after osteoblastic induction,ALP was strongly positive,and at the 10th day,mineralized nodules stained with chinalizarin were jacinth.At the 21th day after adipogenic induction,the adipocytes were stained with oil red O.BMSCs grew well around or in pores of the HA/TCP bone graft scaffold and could be seen using both fluorescence microscopy and scanning electron microscopy.The MTT test assay showed that the HA/TCP couldn't inhibit the proliferation of BMSCs.Conclusion BMSCs have a good biocompatibility with a HA/TCP bone graft scaffold.
